BEP Marine 4-Stud 500A Pro Installer Bus Bar

The BEP Marine Pro Installer 4-Stud Bus Bar is a 500A distribution bar with long threaded studs and a clear polycarbonate cover.

The 500A rating is the thing to notice, since the three, five and eight-stud Pro Installer bars are rated 650A. That makes stud count and current capacity independent choices in this range, and it is worth checking the rating rather than assuming it scales with size.

Five hundred amps still covers most battery, charging and inverter distribution on a boat, and four studs suits a system with a moderate number of heavy circuits. Long threaded studs take several large lugs each where circuits share a connection point.

Snap-out side skirts allow cable entry from additional directions, and radiused ends improve routing for thick conductors approaching the bar. The common interconnection height clusters it with other Pro Installer components, and plated brass nuts on stainless studs prevent galling during installation and service.
